REVERSE OSMOSIS & NANOFILTRATION

PERFORMANCE UNDER PRESSURE

Compared to other filtration technologies that rely on a screen or filter to remove particles, reverse osmosis (RO) and nanofiltration (NF) are pressure-driven separation processes that employs a semi-permeable membrane and the principles of cross-flow filtration.

We provide the most widely used RO and NF technologies in the world—trusted by municipalities, manufacturers of all types, small businesses and families wanting clean, healthy water at home.

REVERSE OSMOSIS AND NANOFILTRATION TYPES

Driving technology forward is what we do best. With decades of global experience in working with the most difficult problems in purifying water or liquid streams, regional technical support, and industry-leading innovations, our RO and NF technologies bring world-trusted, top-tier technology to your water filtration needs.

Brackish Water 4"

These DOW FILMTEC™ Brackish Water RO Elements with a 4-inch diameter offer consistent, exceptional system performance in light industrial brackish water applications, helping to minimize the total ownership cost of water treatment systems.

Brackish Water < 4"

These DOW FILMTEC™ Brackish Water RO Elements with a diameter less than 4 inches are industry standards for reliable operation and production of high quality commercial water at low pressure operations.

Nanofiltration 8"

These DOW FILMTEC™ NF Elements with an 8-inch diameter provide exceptionally high productivity and are designed to remove a high percentage of TOC and THM precursors while having a medium to high salt passage and medium hardness passage.

Nanofiltration 4"

These DOW FILMTEC™ NF Elements with a 4-inch diameter provide high-productivity performance while removing a high percentage of minerals and organic compounds with low energy usage and reduced power consumption and cost.

Process Separations 4"

These DOW FILMTEC™ NF Elements with a diameter less than 4 inches are high-productivity elements ideal for removing a large percentage of organic compounds with partial softening at low operating pressures.
